Key Points Of Application Technology Of Extruded Anti-Bird Net For Fruit Trees

At present, more than 98% of orchards have suffered from birds trouble, and the annual economic loss caused by birds trouble is up to 700 million yuan. After many years’ research, scientists have found that birds are sensitive to color, especially blue, orange and yellow. Therefore, on the basis of this research, researchers have invented a mesh made of polyethylene as the basic material, covering the whole orchard, which was applied for apples, grapes, peaches, pears, cherries and other fruits, and functioned well.

I. Color selection

It is generally recommended to use yellow extruded anti-bird net in mountain areas and blue and orange extruded anti bird netting in plain areas. Birds do not dare to approach to the nets in the above colors, which can not only prevent birds from pecking fruit, but also prevent birds from hitting the net. The effect of bird prevention is obvious. It is suggested that transparent wire mesh should not be used in production. This kind of wire mesh does not have the function of driving away the birds, and birds are easy to hit the mesh.

II. Selection of mesh opening and mesh length

Depending on the size of local birds, for small individual birds such as sparrow, extruded anti-bird net with 3cm mesh openings can be selected; For larger individual birds such as magpie and dove, extruded anti-bird net with 4.5cm mesh openings can be selected. Generally, the wire diameter of extruded anti bird netting is 0.25 mm. The net length shall be purchased according to the actual size of the orchard so as to cover the whole orchard. The length and width of online products in the market shall be 100-150 meters in length and 25 meters in width respectively.

III. Selection of support height and density

When installing extruded anti bird netting for fruit trees, the first thing to do is to lay the support. The support can be purchased as the finished one or welded with galvanized pipe and triangle iron. The buried part shall be welded with cross to resist lodging. Iron ring shall be welded on the top of each support, and each shall be connected by iron wire. After the support is laid, it should be firm and durable, and should be about 1.5 meters higher than the height of fruit trees, so as to facilitate ventilation and light transmission. Generally, the support density can be controlled by 5 meters in length and 5 meters in width. According to the row spacing and orchard size, the denser the support density is, the better the effect will be, but the higher the cost will be. You can buy extruded anti bird netting of corresponding width according to the width to save materials.

IV. Sky net and side net erection

Extruded anti bird netting for fruit trees should be erected in three dimensions. The net at the top of the tree crown is called the sky net. The sky net is put on the wire pulled at the top of the support. Pay attention to the tight junction without any gap. The outer net of tree crown is called side net. The junction of side net shall be close and the length shall reach the ground without leaving any gap. The sky net and the side net are closely connected to prevent birds from entering the orchard.

V. The installation time shall be determined

Extruded anti bird netting for fruit trees is only used to prevent birds from harming fruits. Generally, the bird net is installed when birds start pecking the fruits and it is about 7 to 10 days before the fruits mature. After the fruit is fully harvested, it can be taken down for preservation to prevent it from being exposed to aging in the field and affecting its service life.

VI. Maintenance and preservation of extruded anti bird netting for fruit trees

Inspection shall be carried out at any time after the installation of extruded anti bird nettings for fruit trees, and repair it in time if any damage is found. After the fruits are harvested, carefully take down and roll extruded anti bird netting for fruit trees, pack it up and put it in a cool and dry place for storage, and then use it when the fruit matures in the next year. Generally, it can be used for 3-5 years.
